Choosing among relays, contactors, and industrial switches comes down to what the part must do in your control panel. The options here run from an USD 8 SSR spare to a USD 350 12-relay board, with a USD 319.99 new power relay and a USD 79 parts PCB in between-a USD 342 spread. Do you need a defined replacement, a cheap backup, a multi-relay board, or a repair project?
Quick take
For a new relay with a 115/125 VDC coil and DC operation, choose the Struthers-Dunn 219XBX69P-115/125VDC. For a low-cost SSR spare, choose the INDUSTRIAL SPARE SSR-40DA RELAY 24/480V NSNP. For 12 relay ports on one board, choose the 0907 PB 12-RELAY INDUSTRIAL PCB BOARD. For a parts/repair PCB, consider the AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06.

Product notes
Struthers-Dunn 219XBX69P-115/125VDC
This is the only new power relay in the group with a specified 115/125 VDC coil and DC current type. It is rated for commercial, control equipment panel, and industrial applications. At USD 319.99, it sits near the top of the price range but gives you a defined single relay rather than a bare PCB. The limitation is capacity: you get one relay, not 12 ports. If your cabinet needs many switching positions, the 0907 PB board at USD 350.00 offers more for about USD 30 more.
AMS 4419 Rev G
The AMS 4419 Rev G is sold for parts or not working, and the boards have not been powered on or functionally tested. At USD 79.00, it is cheaper than the new power relay and the 12-relay board, but there is no guarantee of functionality. Choose it if you need a donor PCB for connectors, traces, or components and you can test and repair. Skip it if you need a relay that works immediately; a new power relay or the 0907 PB board are safer choices at higher prices.
INDUSTRIAL SPARE SSR-40DA
At USD 8.00, this SSR-40DA is the lowest-priced product here and the only solid-state option. It is listed as new, open-box, and as an industrial spare, so it works as a cheap standby for a 24/480 V circuit. The trade-off is that it is a bare relay component, not a control board, so it cannot offer the 12 relay ports of the 0907 PB board. If you already have the socket and wiring for an SSR, this keeps your cost minimal; for a complete multi-relay platform, move up the price scale.
0907 PB 12-RELAY INDUSTRIAL PCB BOARD
The 0907 PB is the highest-priced product at USD 350.00 and the only one with 12 relay ports on a single PCB. That makes it the natural pick when your system needs multiple switching positions in one board. The open-box new condition means it is not sold as a used or for-parts item. The limitation is the cost: at USD 350.00, it is far above the USD 8.00 SSR spare, so be sure 12 relay ports are what your application needs. If you need only one power relay, the Struthers-Dunn unit at USD 319.99 covers that for less.
Final recommendation by use case
- New power relay with a specified DC coil voltage: Struthers-Dunn 219XBX69P-115/125VDC.
- Low-cost solid-state spare: INDUSTRIAL SPARE SSR-40DA RELAY 24/480V NSNP.
- 12 relay ports on one PCB: 0907 PB 12-RELAY INDUSTRIAL PCB BOARD.
- Parts/repair PCB if you can troubleshoot: AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06.
The practical takeaway: pay for the relay function you need. The USD 8 SSR spare and USD 350 12-relay board serve very different jobs.
